Television cameras caught Evans dragging his middle finger across his face as he smiled at what appeared to be a heckler during the second quarter of the game while he was at the free-throw line.
Evans, however, said he was jokingly making the gesture toward the Clippers bench and at teammates Blake Griffin and DeAndre Jordan, not at a heckler.
"We have these nicknames that we say to each other on the team," Evans said. "In practice, we may call someone 'cheesecake' or we may call someone 'cupcake' and on the play D.J. and Blake were saying, 'Good job, cupcake.' And if you see the replay, I'm looking at them while I'm doing it. That's who I'm looking at. It's an inside joke. If you look at it, I'm smiling and looking at D.J. and Blake."
Evans has averaged 2.2 points and 5.3 rebounds in 45 games for the Clippers this season.
